Pilz safety switches – wiring methods for safety switches

1. The installation of the safety grating must be able to effectively prevent bypassing the detection area of the safety grating and contacting the dangerous moving parts, that is to say, the detection area of the installation grating can not have a blind spot, if the top or bottom of the safety grating has a fixed guard, the guard should be able to ...

1. Selection of relay coil application power supply Under normal circumstances, most of the relays of direct current are selected in the circuit design, and the types of power supplies used in relays can also be considered according to the characteristics of the control circuit. Secondly, it is necessary to think about the power consumed by the relay, and assume that the relay coil is supplied ...

Recently, the "core shortage problem" has been plaguing major industrial control brand manufacturers, from safety PLCs and inverters, to safety door locks, etc., generally because of the lack of chips, resulting in longer delivery times, and some even unable to deliver the goods at all. This has created a "difficult problem" for the friends in the electrical design department.

With the advancement of history, people have experienced the transformation from light industry to heavy industry, and then entered the era of automation brought about by innovation in the field of electronic computer technology and other scientific and technological fields. 　　The wisdom and potential of human beings are limitless, and today in the 21st century, we are experiencing new ...

Short-circuit method: when FD is displayed, it means that the safety loop is disconnected, at this time, the safety relay CC is disconnected, and the indicator light on the operation board is extinguished, first check whether the safety loop power supply fuse 1F1 (the 6th from the left in the lower row behind the control cabinet) is fused; Second, when the maintenance needs to be shorted, please ...

Requirements for servo feed systems 1. Wide range of speed regulation 2. High positioning accuracy 3. There is sufficient transmission rigidity and high speed stability 4. Fast response, no overshoot In order to ensure productivity and processing quality, in addition to the requirement of high positioning accuracy ...

The main function of a thermal relay is to protect the motor. The new electronic thermal relay has protection against overload, overcurrent, blocked rotor and various phase faults, current unbalance, interphase short circuit, inter-turn short circuit or overvoltage, undervoltage and so on. In the process of using thermal relays, we should ...

PILZ PILZ SAFETY RELAYS ARE THE MAIN COMPONENTS FOR CONTROL CIRCUITS AND MONITORING AND PROTECTION SYSTEMS FOR ELECTRIC LOCOMOTIVES. WHEN THE ELECTRIC LOCOMOTIVE IS RUNNING, WHEN THE MOTORS, ELECTRICAL APPLIANCES OR CONNECTION LINES IN THE MAIN CIRCUIT AND AUXILIARY CIRCUIT FAIL, THE FAULT CAN BE REPLACED BY THE PILZ SAFETY RELAY OF THE CORRESPONDING MONITORING AND PROTECTION SYSTEM.

1) The installation of the switch panel should be after the installation of the lamp, and the switch must be connected in series on the live line; Application of sealed or protected sockets in wet locations; The allowable deviation of the verticality of the panel is not more than 1mm; The gap between the panels installed in rows should not be greater than 1mm. 2) Where the socket must be facing the switch panel ...

Power supply: AC: Terminals A1 and A2 are connected to the power supply, and the ground wire is connected to the protective ground. DC: A2 is connected to the ground terminal of the power supply. Start-up loop: Auto-start: S13-S14 shorted. Manual monitoring start-up mode: S33-S34 ...

Key in Pocket has attracted attention since its introduction as an alternative to tagout lockout, as it not only improves work safety and optimizes workflows, but also provides convenience and productivity for workers in the field. Key in pocket is actually IAM ( ...

Since its launch, Pilz's flagship product, the configurable and safe small controller PNOZmulti, has been impressed by users for its robustness, flexibility and ease of operation. PNOZmulti Configurator as a configuration tool for the safe small controller PNOZmulti ...

The most common ones are the following: (1) Contact failure 1. The phenomenon that cannot be disconnected due to mechanical occlusion of the contact (the needle-like protrusion formed on the contact and the pit biting each other), fusion welding, or cold welding. 2. Due to the contact resistance becoming large and unstable, the circuit cannot be normal ...

(1) Measure the resistance of the contact: use the resistance of the multimeter to measure the resistance of the normally closed contact and the moving point, and the resistance value should be 0; The resistance between the normally open contact and the moving point is infinite. From this, it is possible to distinguish which is a normally closed contact and which is normally open. (2) Coil resistance: multimeter R...

1. The structure/working principle of the two is different Mechanical relays consist of an iron core, coils, and contacts. When the coil is energized, the current in the coil generates a magnetic field that makes the contacts act, thus completing the working principle of the mechanical relay. Solid state relays are made up entirely of electronic components. That...

With 168,000 employees in 17 countries, steel giant ArcelorMittal is the world's leading steel producer. The Ghent site in Belgium alone produces more than 6 million tons of steel per year. Its industries mainly include automotive and mobility, construction, energy, and packaging. 　　As the world's leading steel ...

The development of IT technology is changing all walks of life, automation is no exception, the degree of networking of production equipment and the use of standard protocols such as Ethernet for physical transmission of data has greatly increased, standardized protocols such as OPC UA allow access to controllers through IT systems, making data communication changeable.

In the process of adjustment, cleaning, maintenance and repair of mechanical equipment, the unexpected start of equipment due to various reasons is one of the most typical accident causes. Many companies may also be struggling with how to effectively control unplanned start-ups during maintenance. In order to have ...

PILZ SAFETY RELAYS GENERALLY CONSIST OF AN IRON CORE, COILS, ARMATURES, CONTACT REEDS, ETC. As long as a certain voltage is added to both ends of the coil, a certain current will flow through the coil, resulting in an electromagnetic effect, and the armature will overcome the tensile force of the return spring under the action of electromagnetic force attraction to ...

Positional proportional gain 1. Set the proportional gain of the position ring adjuster; 2. The larger the setting value, the higher the gain, the greater the stiffness, and the smaller the position lag under the same frequency command pulse. However, too large a value may cause oscillation or overshoot; 3. Parameter value ...
